主 题：solar greenhouse root zone heating substrate temperature air temperature tomato trough cultivation
摘 要：Heating greenhouse is indispensable for plant development particularly in winter when the air temperature is *** that sense,root zone heating is more energy-saving than traditional air *** current work was devoted to the study of the effect of two root zone heating systems based on carbon crystal electrothermal film and low temperature hot water pipe on the microclimate and tomato yield in solar *** their performance was tested in the coldest period of winter in Yongqing County of Hebei *** results showed that the use of root zone heating system can improve the average substrate temperature by 6.8℃.This microclimate improvement had a positive impact on tomato *** output per square meter has increased by 19%compared to the *** was also noted that the presence of root zone heating leads to a decrease in the development of disease in heated *** on these results,the root zone heating system can be an effective method of improving the environmental temperature of crop plant,which is of great significance for increasing crop yield.
